HERBERT A. HUMPHREY, OF WESTMINSTER, ENGLAND.

SPECIFICATION forming part of Letters Patent No. 737,932, dated September 1, 1903. Application filed August 1l, 1902- Serial No. 119,333. (No model.)

To all whom zit may concern:

Beit known that I, HERBERT ALFRED H UM- PHREY, a citizen of England, residing at 3S Victoria street, Vestminster, in the county of London, England, have invented a certain new and useful Centrifugal Apparatus for Purifying Gases, (for which I have applied for a patentin Great Britain, dated November 2, 1901, No. 22,13l,) of which the following is a specification.

This invention, which originally formed a part of my application Serial No. 106,037, relates to certain new and useful improvements in apparatus for purifying gases and in which the gases are caused to travel through aseries of chambers or compartments each provided with a centrifugal fan. These chambers or compartments are arranged in such relation to each other that the gases owing to the action of the fans are delivered from one chamber or compartment to an adjacent chamber or compartment. Each of the chambers or compartments is supplied with a suitable quantity of water ilowing in a direction 0p` posite to that direction in which the gases travel,and the chambers or compartments are further provided with an adjustable means, hereinafter set forth, to permit the passage of the water from one chamber or compartment to the other, as well as to increase or decrease the level of the water in each chamber or compartment as occasion requires.

The object of the invention is to construct an apparatus for purifying gases which shall be simple in its construction, strong, durable, efficient in its use, and comparatively inexpensive to set up.

To this end the invention consists of the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particnlarlypointed outin the claimshereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like reference characters denote corresponding parts, and in which- Figure l is a longitudinal sectional view of the apparatus, and Fig. 2 is a vertical section through the compartment C2 on the line @c or.

Referring to the drawings by reference characters, A denotes a casing constructed with inwardly-extending portions at various intervals, as at A A2 A3 A4 A5, forming the casing into a series of chambers or compartments C C2 C3 C4. The bottom of the cham bers or compartments are flattened, as shown in Fig. 2. Each end of the casing A is open, and communicating with one open end of the casing A is an inlet-pipe d for the gas, and communicating with the other open end of the casing is an outlet-pipe h for the gases after they have passed through the apparatus. The outletpipe h carries a suitable water-spraying device e, communicating with a water-supply and adapted to direct water into the casing A. The water when it is caused to enter the casing A by means of the spraying device flows down intoA the bottom of the chamber or compartment C4 and is directed from said compartment C4 to the adjacent compartments by means of coupling devices, which will now be referred to.

The coupling device between the chambers or compartments C8 and C4 consists of two vertical members l2, which are preferably in the'form of hollow tubes and screw-threaded at their top and bottom. The lower ends of these vertical members 1 2 are connected together by means of a longitudinal member f', the latter being connected to the lower screw-threaded end of the members 1 2 by means or" the three-way couplings Il 7c. The upper end of the member l is adapted to eX- tend through the bottom of and project into the c'hamber or compartment C4. The upper end of the member 2 is adapted to extend through the bottom of and project into the chamber or compartment G3. The bottoms of the chambers or compartments C3 O4 are provided with screw-threaded openings to receive the screw-threaded upper ends of the members 'l and 2.

The coupling device between the chambers or compartments C2 and O3 consists of two vertical 'mem bers 3 4:, which are preferably in the form of hollow tubes and screw-threaded at their top and bottom. The lower ends of these vertical members 3 4 are connected together by means of a longitudinal member` f2, the latter being connected to the lower IOO screw-threaded end of the members-3 4 by means of the three-way couplings Z m. The

upper end of the member 3 is adapted 'to extend through the bottom of and project into the chamber or compartment C3 at the oppositev side of said bottom from that at which the member 2 enters said chamber. The upper end of the member 4 is adapted to extend through the bottom of and into the chamber or compartment C2. The bottoms of the chambers or compartments C2 and C3 are provided with screw-threaded openings to receive the screw-threaded upper ends of the members 3 4c.

The coupling device between the chambers or compartments C and C2 consists of two vertical members 5 6, which are preferably inthe form of hollow tubes and screw-threaded at their top and bottom. The lower ends of these vertical members 5 6 are connected together by means of a longitudinal member f3, the latter being connected to the lower screw-threaded end of the members 5 6 by means of the three-way couplings n o. The upper end of the member 5 is adapted to extend through the bottom of and project into the chamber or compartment C2 at the opposite side of said bottom from that at which the member 4 enters said chamber. The upper en'd of the member 6 is adapted to extend through the bottom of and extend into the chamber or compartment C. The bottoms of the chambers or compartments C and C2 are provided withscrew-threaded openings to receive the screw-threaded upper ends of the members 5 6.

At the end of the series of chambers or compartments is an outlet for the water, through whichthewater is caused to flow by the pressure of 'the incoming gas, the pressure ofthe gas being greater than atmospheric pressure. rThis outlet consists of the vertical member 7, which is preferably in the form of a hollow tube and screw-threaded at its upper and lower ends. To the lower screwthreaded end of the member 7 is attached a three-way couplingp, which'in turn connects the member '7 to any suitable discharge medium, as at 7, by the longitudinal member f4. The upper end of the tube 7 is adapted to extend through the bottom of and project into the chamber or compartment C-l at the opposite side of said bottom from that at which the member 6 enters said chamber. 'Ihe bottom of the chamber or compartment C' is provided with screw-threaded openings to receive the screw-threaded upper ends of tubes 6 and 7. Nuts g are mounted upon the upper ends of the members l, 2, 3, 4, 5, 6, and 7, below the bottom of the casing A for vertically adjusting said members.

The vertical members of the coupling devices may thus be adjusted, so as to protrude .more or less into the chambers or. compartments, and thereby vary the level of the water in said chambers or compartments. Through the casing ot extends a shaft b, which is journaled in suitable boxes B B, attached to the inlet and outlet pipes d and h. These journal-boxes may be of any suitable construction, and it is therefore unnecessary to describe them in detail. Mounted onl the shaft b. are centrifugal fans a d d d, one of said fans being adapted to move in each of the chambers or compartments C', C2, C3, and C4. Each of the fans d consists of a circular disk having diagonally-disposed blades attached thereto.

It is obvious that although the apparatus herein described is expressly designed for bringing gas and liquid into contact for the purpose of purifying the gas it is equally applicable for bringing gases and liquids into contact in order to effect chemical or physical reaction between the gas and the liquid, or even merely to cool the gas.
